Advanced PulseFinding Setup Section
The
PulseFinding Technique
mode is disabled when the
Percent of Phase Overcurrent
Trip Reached
, the
Percent of Ground Overcurrent Trip Reached
, and the
Percent of
Negative Sequence Overcurrent Trip Reached
setpoints are all set to the
Off
state.
Percent of Phase Overcurrent Trip Reached
This is configurable to improve the sensitivity to lower-magnitude faults. (Default: 50%;
Increment: 20%, 50%, 80%, and Off)
Note:
When using the PulseFinding technique with the IntelliTeam system this setting
must be ≥50%.
Percent of Ground Overcurrent Trip Reached
This is configurable to improve the sensitivity to lower magnitude faults. (Default: 80%:
Increment: 20%, 50%, 80%, and Off)
Note:
When using the PulseFinding technique with the IntelliTeam system this setting
must be ≥50%.
Percent of Negative Sequence Overcurrent Trip Reached
This is configurable to improve the sensitivity to lower magnitude faults. (Default: 50%;
Increment: 20%, 50%, 80%, and Off)
Note:
When using the PulseFinding technique with the IntelliTeam system this setting
must be ≥50%.
Global Timers Section
Test Sequence or PulseFinding Technique Loss-of-Source Timeout
When this timer expires, the loss of source is considered to be permanent, the
PulseFinding Technique Sequence
or
Test Sequence
operation is cancelled, and
further automatic operation is stopped. This timer resets when the IntelliRupter fault
interrupter is manually closed after power returns. (Range: 10-600; Step: 1; Default:
300 seconds)
Block Test on Backfeed Timeout
If backfeed voltage remains present for longer than the specified time, the IntelliRupter
fault interrupter remains open and goes into the
Lockout
state. (Range: 10-600; Step: 1;
Default: 300 seconds)
IntelliTeam Event Memory Timer
The IntelliTeam system considers system protection to be active for the duration of this
timer. Configure sufficient time to ensure devices such as substation breakers or upstream
protection devices complete automatic operation before this timer expires to indicate
the end of the event and the system is stable. (Range: 1-900 seconds; Step: 1; Default: 45)
Minimum Time Between SEF Current Spikes
This configures the minimum time between current spikes before they are counted.
(Range: 10-1,000 ms; Step 1; Default: 50) It applies to the
SEF Trip on Current Spike
mode on the
Setup>Protection>General Profile>Initial Trip–Additional Features
screen.
